A fuse state detection circuit is comprised of a first fuse element, a second fuse element, and an output for carrying an output signal, the output signal represents a first logic state when the first fuse element is blown and the second fuse element is unblown and the output signal represents a second logic state when the first element is unblown and the second element is blown. The fuse state detection circuit produces an output signal that whose state is recoverable from to a negative triggering event and is capable of resolving itself to the correct state without the need for a reset pulse. Methods of using the fuse state detection circuit, such as a method of using fuse elements to control a setting within an electronic circuit, the improvement comprising using a pair of fuse elements to control a single setting, are also given.
